VB editor

Seems like the Mach3 VB editor is real straight forward editor. But I am having issues with it. I have been playing around with the Ref All Home button script (HiddenScript.m1s). On many, many occasions I make my changes, Save, and close it. When I go back and look at the file, the changes have not been saved. But then sometimes they are saved.

So, any ideas what is going on? Something this simple is driving me nuts.

Thanks.
